On Launch Pad 39A at NASA's Kennedy Space Center, STS-133 crew members receive instruction on the operation of the pad's slidewire basket system emergency exit training as part of the Terminal Countdown Demonstration Test (TCDT).

TCDT provides each shuttle crew and launch team an opportunity to participate in various simulated activities, including equipment familiarization and a launch countdown. Space shuttle Discovery and its STS-133 crew will deliver the Permanent Multipurpose Module, packed with supplies and critical spare parts, as well as Robonaut 2, the dexterous humanoid astronaut helper, to the International Space Station. Launch is targeted for Nov. 1 at 4:40 p.m. For more information on the STS-133 mission, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts133/. Photo credit: NASA/Kim Shiflett
